Learning a new language boosts brain power - whatever your age

Learning another language boosts brain power - no matter how old you are, according to new research.

Tests carried out on students of all ages suggest that acquiring a new language improves a person’s attention - after only a week of study.

Researchers also found that the benefits for mental agility could be maintained with regular practice.

Edinburgh University researchers assessed different aspects of mental alertness in a group of 33 students aged 18 to 78 who had taken part in a one-week Scottish Gaelic course.

The researchers tracked people’s attention levels via a series of listening tests, including the ability to concentrate on certain sounds and switch the attention to filter relevant information.

They compared the results with those of people who had completed a one week course - but not involving learning a new language - and with a group who had not completed any course.

After one week, improvements in attention were found in both groups participating in intensive courses, but only those learning a second language were significantly better than those not involved in any courses.

The improvement was found for all ages, from 18 to 78, which researchers say demonstrates the benefits of language learning also in later life.

Nine months after the initial course all those who had practised five hours or more per week improved from their baseline performance.

The researchers say this shows the mental skills gained from language learning can be maintained if speakers practise continuously.

Lead researcher Doctor Thomas Bak, of the School of Philosophy, Psychology and Language Sciences, said the results confirm the cognitive benefits of language learning.

Dr Bak said: “I think there are three important messages from our study: firstly, it is never too late to start a novel mental activity such as learning a new language.

“Secondly, even a short intensive course can show beneficial effects on some cognitive functions. Thirdly, this effect can be maintained through practice.”

The study was completed with the help of students from Sabhal Mor Ostaig, the National Centre for Gaelic language and culture on the Isle of Skye, which forms part of the University of the Highlands and Islands.

Professor Boyd Robertson, Principal of the College, added: “I welcome the study’s identification of the cognitive benefits gained from learning Gaelic on our short courses.

“Audits have previously found that students have derived social benefits from these courses and this new research confirms that short course study at the College confers threefold benefits - linguistic, cognitive and social.”
